Checking function and leak-tightness

Before you hand the product over to the operator:
▶
Check the gas line, the flue gas installation, the heating
installation and the hot water pipes for leaks.
▶
Check that the air/flue pipe and condensate drain pipe-
work have been installed correctly.
▶
Check that the front casing has been installed correctly.
7.16.1 Checking the heating mode
1. Make sure that there is a heat requirement.
2. Call up the Live Monitor.
◁
If the product is working correctly, the display shows
S.04.

7.16.2 Checking the hot water generation
1. Open a hot water valve all the way.
2. Call up the Live Monitor.
◁
If the hot water generation is working correctly, S.14
appears in the display.
7.16.3 Checking the cylinder charging
Note
2
Cylinder charging is deactivated ex-works and
must be activated during initial start-up.
The cylinder charging of the shift-load cylinder is only active
if Comfort mode is switched on. If Comfort mode is activated,
the symbol "C" appears in the display ( Operating instruc-
tions).
When cylinder charging is switched on, the following temper-
atures can be set for the hot water temperature (see operat-
ing instructions):
–
Minimum temperature 50 °C
Maximum temperature 65 °C
When cylinder charging is switched off, the following temper-
atures can be set for the hot water temperature:
–
Minimum temperature 35 °C
Maximum temperature 65 °C
If cylinder charging is switched off, the cylinder is not held
at temperature. If you draw off water, the boiler switches on
and, in this case, only operates on the through-flow principle.
▶
The product is equipped with an automatic Anti-legionella
function; if the temperature in the domestic hot water
cylinder falls below 50 °C, the cylinder is heated up to
70 °C once every 24 hours. If required, in consultation
with the operator, switch the Anti-legionella function off
using diagnostics code D.074.
